Horak (1990: 298). <i>Humidicutis multicolor</i> was described from Sri Lanka with records in Tierra del Fuego, Southern Argentina, and New Zealand (Horak 1979, Horak 1990). <i>Humidicutis multicolor</i> also has a blue pileus context when exposed but differs from <i>H. pindorama</i> by having purple-lilac-blue pigments in the pileus and stipe, and by the much smaller basidiospores (5.5–7 × 4–5 µm) and basidia (20–45 × 6–7 µm) (Horak 1990). <i>Humidicutis pindorama</i> is macroscopically like <i>Humidicutis luteovirens</i> (Horak) Horak (1990: 296) from New Zealand, but the latter has smaller basidiospores (6–8 × 3.5–4.5 µm) and basidia (25–42 × 6–7 µm) (Horak 1990). <i>Humidicutis arcohastata</i> (A.M. Young) A.M. Young (2005: 159) in Australia differs from <i>H. pindorama</i> by the conical to campanulate pileus and by the presence of purple-mauve tints on the pileus and stipe (Young 2005). <i>Humidicutis helicoides</i> (A.M. Young) A.M. Young (2005: 159) has lime green lamellae rather than green to orangy yellow lamellae with a deep orange edge (Young 2005). Also, <i>H. pindorama</i> lacks the spiral bands of encrusted pigments found in the pileipellis hyphae of <i>H. helicoides</i>. <i>Humidicutis taekeri</i> (A.M. Young) A.M. Young (2005: 159) is easily distinguished from <i>H. pindorama</i> by its brilliant orange lamellae (Young 2005). <i>Humidicutis viridimagentea</i> A.M. Young & K. Syme (2007: 71) differs by the distinctive magenta colouration (Young 2005, Young & Syme 2007). Finally, <i>Humidicutis woodii</i> (A.M. Young) A.M. Young (2005: 159) has a white stipe and lacks the conspicuous toroidal clamp connections (Young 2005) at the basidia base.</p> <p> Only the second species of <i>Humidicutis</i> known from South America, <i>H. pindorama</i> was described based on two specimens from Southern Brazilian Atlantic Rainforest and one from the Amazon Forest, increasing the distribution range of the genus. Basidiomata were found on white sand soils, so this species is probably adapted to soils poor in nutrients. The germinating basidiospores in JS20 are very intriguing and firstly recorded herein.</p>Published as part of <i>Cardoso, Juli Simon, Moncalvo, Jean-Marc, Lodge, D.

There are two species known from the neotropical region: <i>Neohygrocybe subovina</i> (Hesler & A.H. Sm.) Lodge & Padamsee (2013 [2014]: 41) and <i>Hygrocybe ovinoides</i> Lodge, S.A. Cantrell & T.J. Baroni (2004: 1312) combined in <i>Neohygrocybe</i> herein. <i>Neohygrocybe subovina</i>, from USA, also has cheilocystidia and pseudocystidia projecting from the hymenium, but the basidiomata are much darker in colour, the lamellae bruise pink to reddish brown or darker, the basidiospores are globose to subglobose rather than ellipsoid, and the cheilocystidia are vermiform and cylindrical rather than pyriform (Hesler & Smith 1963). <i>Hygrocybe ovinoides</i> produces very small basidiomata which are also dark in colour, but the pilei have a white margin (Cantrell & Lodge 2004). In the microscopy, <i>H. ovinoides</i> lacks cheilocystidia and has hook-like pileocystidia (Cantrell & Lodge 2004). Both <i>N. subovina</i> and <i>H. ovinoides</i> lack the nitrous odour found in <i>N. fumosa.</i></p>Published as part of <i>Cardoso, Juli Simon, Moncalvo, Jean-Marc, Lodge, D.

Eustáquio Neves: photographic subject - memory and image
No full textEsta pesquisa tem como ponto de partida o acesso ao ateliê e aos arquivos de criação do artista Eustáquio Neves. A investigação dos percursos identificados nas obras, esboços, anotações e falas de Neves busca relações entre os processos de criação e a presença comunicante materializada nos trabalhados do artista, visando descobrir de que maneira os procedimentos adotados pelo autor transformam imagens em estandartes que carregam memórias deliberadamente evocadas enquanto povoam universo ficcional com seus próprios tempos e espaços. Neves coloca a fotografia no contexto das artes visuais ao criar imagens complexas nas quais o clamor político e as marcas do processo – tanto fotográfico quanto extrafotográfico – se impõem. A presença resulta, portanto, de investimento semântico que perpassa todo o processo de criação e, no caso de Neves, é amplificado pelo uso não convencional desses procedimentos. O estabelecimento de vínculos entre obras, autor e contexto de produção tem como objetivo detectar nexos e recorrências entre os trabalhos de Neves, em suas diversas etapas de desenvolvimento, e questões pertinentes acerca das artes visuais contemporâneas. O tratamento acadêmico do material, feito sob a perspectiva da crítica de processos de acordo com contribuições teóricas de Cecilia Almeida Salles, faz emergir discussões sobre os tempos e espaços fotográficos, autoria, memória e arquivos. Ao lado de Salles aparecem autores que colaboram para uma abordagem interdisciplinar: Vincent Colapietro, Henri Bergson, Edgar Morin, Georges Didi-Huberman, Jacques Rancière e Michel FoucaultThis research has as its starting point the access to the studio and the creation archives of the Brazilian artist Eustáquio Neves. The investigation of the paths identified in Neves' s works, sketches, notes and speeches, seeks to establish relations between the creation processes and the communicating presence materialized in the artist's works, in order to discover how the procedures adopted by the author transform images into manifestos that carry memories deliberately evoked, as they populate a fictional universe within their own times and spaces. Neves places photography in the context of the visual arts by creating complex images in which the process reminiscences - both photographic and extra-photographic - impose themselves, as well as the political statement. Presence therefore results from a semantic investment that permeates the entire creation process and, in the case of Neves, is amplified by the unconventional use of these procedures. The establishment of links between works, author and context of production aims to detect nexuses and recurrences between the material, in its various stages of development, and pertinent questions about contemporary visual arts. The academic treatment is made from the perspective of process criticism in accordance with Cecilia Salles' theoretical contributions and gives rise to discussions about photographic times and spaces, authorship, memory and archives. Alongside Salles are authors who collaborate for an interdisciplinary approach: Vincent Colapietro, Henri Bergson, Edgar Morin, Georges Didi-Huberman, Jacques Rancière and Michel FoucaultConselho Nacional de Pesquisa e Desenvolvimento Científico e Tecnológico - CNP
Cross-Cultural Connections: School Climate and Equity in Germany, Italy, Latvia, and the United States
No full textIn recent decades, much international research has been carried out on school climate and its relationship with learning, socioemotional, and health outcomes (Berkowitz et al., 2017; La Salle, Rocha-Neves, et al., 2021; Pizmony-Levy et al., 2019). Limited research has been carried out to investigate the relationship between school climate and educational inequalities, with particular reference to the results obtained by minoritized students. This contribution focuses on this issue, and it is organized as follows. First, The International School Climate Collaborative, which led to the cross-cultural adaptation of the Georgia School Climate Survey, is presented with normative data for the use of the survey with secondary school students in four countries: Germany, Italy, Latvia, and the United States (La Salle, Rocha-Neves, et al., 2021). Second, the theme of the relationship between School Climate and Educational Equity is focused on the basis of the most recent scientific literature. Third, the theme of the relationship between School Climate and Educational Equity is focused on comparing four countries: the United States, Germany, Italy, and Latvia. Fourth, the practical implications are investigated, focusing on three possible interventions that could be useful for improving the school climate while promoting equity and valuing cultural differences
